Hot Dip Galvanization Q235B Steel Tube Scaffolding Connectors Malleable Cast Iron

Scaffold fasteners are the core connecting components of building support systems, specifically designed to provide secure and reliable rigid connections for steel tube scaffolding. The products are made of malleable cast iron (KT-33 grade) or Q235B steel, treated with hot-dip galvanization or electrophoretic anti-rust coating, ensuring long-term use in harsh construction environments.
